CAN’T SEND MAIL FROM THE E-MAIL BOX AT YOUR WEB HOST? - Aug 6th, 2010


You may be experiencing ISP port 25 blocking.

If you’ve been blocked, you can only SEND email OUT through your Internet Service Provider's outbound (SMTP) mail
servers. If you try to use any other mail servers except theirs, (The mail server at your domain registrar or web host)
you’ll get a “can not connect” error message.

Bell System DSL, Charter Cable, Cox Cable and other ISPs are implementing "port 25 blocking", in an effort to reduce
spam. These are not temporary changes, so you’ll have to work around the issue.

The solution is to change your OUTBOUND SMTP mail server, under "Account Server Settings".

In your mail program, change the outgoing server listed in your e-mail account settings to your ISP’s outgoing e-mail
server and then under “advanced” or “other options” > “outgoing server”, check ”my outgoing server
requires authentication” and enter your ISP’s e-mail username and password. That should get you running again.

You can continue receiving email at your domain name with your current settings. You do not need to change anything to
continue receiving email at your domain name. And you will not usually have your display name and e-mail address
changed. An exception to that is, if you’re using one of the free e-mail services like Hotmail, they may change the
displayed information.

Outlook 2010 Update - I don’t profess to understand it, but in Outlook 2010, all of my outbound settings needed to be
reset to my Inbound server settings with the exception of the outbound port which needed to be reset to Port 587
(advanced tab).
